Guys, I’ve been holding out on you. I have been trying to perfect my at home Khao Soi recipe for the past three years. And about a month ago, I did it.

First, I have to find some way to convey to you my deep love for Khao Soi. And I guess before that I have to explain to you what it is.

Khao Soi - Northern Thai Curry — Wanderings in My Kitchen (1)

Let me back way up here and take you on a bit of a tangent for a minute. When I was in high school and part of French club, we were planning our first ever trip to France. My French teacher told us a story about scent tying viscerally to memory. She recommended we bring something with us to France that was fragrant (perfume being the most obvious example) and to only smell that thing while we were in France.

Then she told us to hold on to that thing and to bring it out later, only in small doses, whenever we wanted to be reminded of France. That scent would only be connected to the time we spent in France and would have transportive abilities.

She was completely right. I now have a “France perfume” that I wear any time I’m traveling there. I brought a bottle before I left to go study in France, before I went to teach there, and every time I’ve been back. Nothing, and I mean nothing, has the ability to knock me straight back to Paris as smelling this perfume.

Khao Soi is my France perfume.

Not literally of course. Let me explain.

Khao Soi is a type of Thai curry. You will find it everywhere in Northern Thailand. But it’s not like regular Thai curry. It’s been heavily influenced by the Burmese people to Thailand’s north, has different spices, and is made with egg noodles instead of rice noodles. Khao Soi is almost exclusively in this part of the country, and it’s not frequently represented on Thai menus internationally.

This means Khao Soi, and all its glorious smells and tastes, are ubiquitously available in Thailand. But as soon as you step out, it disappears. No more Khao Soi. And so the taste creates a connection with the place.

Much like the perfume in France, the scent throws you back – to that time, to that place, to that feeling. I can’t unlink Khao Soi with Thailand, and I also don’t want to.

So, what is Khao Soi?

Khao Soi is a type of Thai curry. It starts off at its base with a regular red or yellow Thai curry paste. Then it gets extra layers of flavor with spices like cardamom, coriander, and nutmeg. Then it gets a sinful creaminess from coconut milk. And finally, you have the egg noodles.

Khao Soi always has two different types of egg noodles, and don’t let anyone tell you differently. You have soft, boiled egg noodles swimming in the curry broth, but you also must have fried, crispy egg noodles in tangled nests to top the bowl. The textural contrast is a dream.

The main protein in this Northern Thai curry is chicken, and for my best recreation I used chicken thighs. The garnishes – as with almost any dish I’ve eat in Southeast Asia – make the meal. Pickled mustard greens, raw shallots, and fresh herbs and chilis are all commonplace on Thai tables when eating Khao Soi.

The only Khao Soi I’ve ever been able to find at Thai restaurants in the US has been Lao Khao Soi. Khao Soi from Laos is not at all Khao Soi from Thailand. It’s made with rice noodles, ground pork, and tomatoes and has no crispy fried egg noodles or coconut milk.

So now you understand what Khao Soi is and why I love it so much. Let’s talk through making it, and why this recipe I’m sharing today has been so different from the other versions I’ve tried recreating.

Khao Soi: The Keys to Success

We tend to have a bias that is homemade = better. While I would argue this is true in a lot of cases, it’s definitely not true in all cases. And curry paste is exactly one of those exceptions.

I have tried very hard to make homemade Khao Soi curry paste. I’ve sought out Thai ingredients from Asian markets, I’ve tried making curry paste in the blender, and I’ve even pounded out a paste using my mortar and pestle alone (which is traditional in Thailand but a LOT of work).

Khao Soi - Northern Thai Curry — Wanderings in My Kitchen (8)

The results have been fine, but they haven’t been worth the effort for the close-but-not-quite renditions of Khao Soi I’ve been able to make. But this time, I cracked the code. It goes like this:

  • Start with store bought red curry paste. I used Arroy D brand for this recipe and had great success. Maesri is another good choice. Compared to other curry pastes these have cumin and coriander which I wanted extra of for this recipe
  • Add in spices that take this from traditional red curry to Northern Thai Coconut Thai Curry – those are coriander, cumin, cardamom, nutmeg and allspice. Investing in some good mild or Madras curry powder will give you many, if not all, of these ingredients
  • Get yourself some palm sugar. I normally use dark brown sugar as a substitute because I can only find palm sugar in Asian markets (and I’m all about making this blog and its recipes accessible for YOU guys). Brown sugar works, but my most successful rendition was made with palm sugar.
  • Use coconut cream AND coconut milk. Shout out to Pups with Chopsticks for this brilliant idea. I think the coconut milk in Thailand being fresher might impact the texture, because all the versions I’ve tried with canned coconut milk alone haven’t had the signature silky texture I remember from Thailand. The version with coconut cream brought me back in an instant.

Making Khao Soi

The noodles

The most labor intensive part of making Khao Soi is preparing the fried egg noodles. It’s not difficult it’s just an extra step to plan for and an extra dish to clean. But it’s a labor of love, because those puffed and crispy egg noodles make this dish the star that it is.

Make sure you’re using fresh egg noodles and not dried egg noodles otherwise you won’t get the same result. Asian grocery stores tend to have fresh egg noodles, and you should absolutely make a trip to buy these.

ProTip: These fried egg noodles make a crazy addictive and delicious snack when sprinkled with salt and chili powder while they’re still hot after cooking

The chicken

Every time we had Khao Soi in Thailand it was with chicken, and since I was going for exact replication I used chicken here as well. But in all honesty, it’s not the star. If you’re vegetarian you could easily omit it and be just fine.

I sear the chicken thighs in the pot I’m cooking the curry in for maximum flavor then remove them. The curry paste and spices bloom in the same oil that was used to brown the chicken, so you get all those crispy flavor bombs incorporated into the soup.

The spices

These spices – their combination – this is the star of Khao Soi. You start with good red curry paste and determine if it’s worthy based by reading the ingredients. Ingredients should include red chili peppers, lemongrass, kaffir lime leaf, galangal, garlic, and shallot at a minimum. Try to find a curry paste that has other spices like coriander seeds and cumin. Arroy D and Maesri are both brands I’ve used with great success.

In addition to the curry paste, you’ll add curry powder. Again, read the ingredients to judge the curry powder’s worthiness. Seek out a mild curry powder or Madras curry powder and make sure it has coriander, fenugreek, cumin, ginger, and allspice.

I couldn’t find a curry powder with cardamom or nutmeg in it so ended up adding my own cardamom and nutmeg to the spice mix. I used the Indo-European Mild Curry Powder for this recipe.

The broth

The broth for Kha Soi is – in a word – luxurious. It’s so rich and creamy and overflowing with flavor. The Khao Soi broth is made by adding coconut cream and coconut milk (both unsweetened) to the curry paste and spices that have been bloomed by cooking them in oil for a few minutes.

After you mix the spices with the coconut milk and cream you add palm sugar, which gives a flavorful sweetness to the Khao Soi. It’s all finished with a healthy squeeze of fresh lime juice. It’s the perfect balance of salty, sweet, sour, spicy.

The garnish

The soup is the masterpiece and the garnishes are the final finishing touches. I beg you to try some of the pickled mustard greens. It sounds like a strange addition, but when it’s all put together with the soup, it just works. Raw shallots, sliced chilis, and lime wedges are also commonplace so you can customize the spice and sourness to your liking.

All of the garnishes sit on top of the crispy fried egg noodles just waiting for their plunge into the Khao Soi.

I’m happy just talking about it.

Bon appétit
